More precisely. When Quagga was licensed, the only version of GPL
was v2. IANAL but my understanding that unless the license includes
the language "either version 2, or (at your option) any later version"
then it is limited to v2 only. Looking at the source there are only three
places where the GPL is mentioned and the "at your option" clause
is missing: COPYING.LIB bgpd/bgp_route.c and bgpd/bgp_snmp.c
